SPRING BED AND SEAT BOTTOM.

SPECIFICATION forming partof Letters Patent No. 639,225, dated December19, 18199. Application filed January 16, 1899. Serial No. 702,351. (Nomodel.)

To ctZZ whom it may concern.-

Be it known that I, JOHN F. GAIL, a citizen of the United States,residing at Kenosha, in the county of Kenosha and State of tVisconsin,have invented a new and useful Spring Bed and Seat Bottom, (Case D,) ofwhich the following is a specification.

For convenience in making cross-reference this application is designatedCase D, and

four other applications for Letters Patent for bed -bottoms executed byme of even date herewith are designated, respectively, Case A, Case B,Case C, and Case E.

This invention relates particularly to spring bed-bottoms formed ofvertical spiral springs united horizontally by tie-rods.

The improvementinvolves the use of a new form of tie-rod which permitsthe use of the simplest form of vertical springs and which allows theready assembling of the parts of the bed-bottom to constitute thefinished structure. There is economy in the read y assembling of theseparts, and there is also economy in the use of a simple form of thespiral spring.

My improvement results in a structure which has a high degree ofstrength, a distribution of strain applied at any particular point, andan even surface.

In the accompanying drawings, Figure l is a plan of a portion of abed-bottom embodying my improvement. Fig. 2 is a detail plan showing asingle spring. Fig. 3 is a detail sectional elevation.

Inasmuch as the general construction of bed-bottoms of this class iswell known, I deem it sufficient to illustrate only portions ofbed-bottoms showing the application of my improvement.

Referring to said drawings, A is a rectangular frame forming the marginsof the bedbottom. This frame may be of Wood or metal; but it ispreferably made of metal rods or bars somewhat heavier than the metal ofthe springs and tie-rods. a

B B are the springs. These are arranged in rows parallel to the sides ofthe frameA and are in vertical position and of spiral form, the upperend of each being formed into a complete ring B by knotting or in anyothersuitable manner. The springs may be cylindric in outline or theymay be conical or double conical. As already stated, it is the object ofthe invention to embody the well-known forms of vertical springs into abed-bottom of superior quality and the parts of which may be readilymade and readily assembled.

C is a tie-rod extending transversely across the bed-bottom and over onerow of springs, near the edges of the latter,and having its endssuitably attached to the frame A. At each spring said tie-rod has threeupward bends C, two over the ring B and one midway between said two.Said two upward bends may be so great as to allow the main portion ofthe tie-rod to rest below the level of the ring B.

C are loops extendinglaterally from the tie rod C at each spring B tothe adjacent spring of the next row or to the side of the frame. Eachloop is formed by folding wire into substantially a V shape, the twoends of the wire C extending first beneath the ring B and over thetie-rod and onward again beneath the ring, and thence around the tie-rodin the outer upward bend C. The apex or portion of the loop the farthestfroni the tie-rod C is bent into vertical form (marked C and passesbeneath and then through the ring B of the adjacent spring of the nextrow of springs.

The transverse row of springs B adjoining the frame A are united to saidframe by one of the tie-rods C, the loops-C extending partially aroundthe said frame.

Another set of tie-rods D D, which, for convenience, I term key-rods,are arranged at right angles to the tie-rods C. These extend centrallyover the longitudinal rows of springs B and through the vertical part Cof each loop C in the row of springs traversed by said key-rod. The endsof the key-rod D may be suit-ably secured to the frame A, preferably inengagement with a loop C engaging the frame at that point, the rodreaching through the loop.

It will now be seen that the bed-bottom herein described consists ofonly five kinds of partsnamely, the frame A, the springs B, the tie-rodsC, the loops C and the straight tie-rods D D; and it will now beunderstood that the assembling of these parts to form a completebed-bottom is a simple process involving only the use of the hands and asimple bending-tool for securing the ends of the tie-rods. The frame maybe first put into position and the springs then placed in rows withinthe frame. The tie-rods O are then put into position with reference tothe springs and the frame, and the ends of said tie-rods bent around theframe or secu red in any suit able manner. The loops 0 are applied tothe tie-rods C after the latter are applied to the frame and springs.The key-rods D are last put into position by passing them over thesprings transversely to the tie-rod C and beneath the loops, the ends ofsaid key-rods D being secured, as by bending around the frame orotherwise. This results in a very positive interconnection of thesprings and the forming of such a surface as will not yield unduly atany one point, pressure at any point involving the depression of aconsiderable area of the bed-bottom surface. The fact is also to benoted that the key-rods D, extending midway over the rings B, preventthe central portion of the spring from pushing upward through the ringB, as is sometimes the case when the upper portion of the spring is leftunprotected.

It should be noted that the loops pass or enter the plane of thespring-rings only far enough to let the key-rods pass under strain.

It will be understood that the number of tie-rods C will depend upon thenumber of rows of springs extending in the direction of said tie-rods.It will also be understood that my invention may be applied tospring-seats and that the foregoing description is applicable tospring-seats as well as to spring bedbottoms.

The spring herein described is also described, but not separatelyclaimed, in the applications designated as Case A, Case 0, and OaseE, towhich reference has been herein made.

I claim as my invention- 1. The combination of spiral springs havingtheir ends formed into rings, tie-rods extending across said springs,lateral loops extending at their apex through the rings of one row ofsprings and thence laterally to the rings on which said tie-rods rest,the ends of said loops passing between the tie-rods and saidlast-mentioned rings, and thence onward again past the rings and thencearound said tie-rods, and key-rods engaging said springs, tie-rods, andloops, substantially as shown and described.

2. The combination of a rectangular frame, spiral springs having theirends formed into rings, tie-rods extending across said springs, lateralloops extending at their apex through the rings of one row of springsand thence laterally to the rings on which said tie-rods rest, the endsof said loops passing between the tie-rods and said last-mentionedrings,

and thence onward again past the rings and gaging said springs,tie-rods, and loops, substantially as shown and described.

3. The combination of spiral springs having their ends formed intorings, tie-rods extending across said springs and having upward bends,G, at each of said springs, lateral loops extending at their apexthrough the rings on which said tie-rods rest, the ends of said loopspassing between the tie-rods and said last-mentioned rings, and thenceonward again past the rings and thence around said tie-rods, andkey-rods engaging said springs, tie-rods, and loops, substantially asshown and described.
